An appeals court on Thursday overturned the convictions of two women accused in the beating and stabbing of a man who they said made unwanted sexual advances to them in Greenwich Village two years ago.

One of the women, Terrain Dandridge, whom a jury found guilty of second-degree gang assault, had her conviction reversed and indictment dismissed; as a result she can no longer be tried on those charges. A four-judge panel of the Appellate Division in Manhattan ruled that there was not enough evidence to support a guilty verdict for Ms. Dandridge. She had been sentenced to three and a half years in prison.

The second woman, Renata Hill, who was found guilty of second-degree gang assault and third-degree assault, had her gang assault conviction vacated, but she can be retried on the charge. The court ruled that the judge’s instructions to the jury on the charge were erroneous and that therefore her conviction could not be upheld.

She was sentenced to eight years in prison, but if the Manhattan district attorney decides against further prosecution, she is likely to be released because the maximum penalty for the third-degree assault is a year and she has already been in prison longer than that.

Alexis Agathocleous, the lawyer who handled Ms. Hill’s appeal, said he was pleased and was hoping “that the district attorney’s office will also do the right thing and dismiss the remaining charge.”

The appeals for Patreese Johnson and Venice Brown are still pending, but let’s hope that they’re as or more successful than these. I also hope that, as Agathocleous says, the DA will do the right thing and drop these sham charges.
